This invention relates to new and useful improvements in tools and moreparticularly to an implement whereby battery clamps can be removed in aconvenient and easy manner.

5 An important object of the present invention is to provide a tool ofintact construction which can be easily engaged with a battery clamp topermit spreading of the clamp to facilitate removal of the same from thebattery post.

Other important objects and advantages of the invention will becomeapparent to the reader of the following specification.

In the drawings:

Figure 1 represents a vertical sectional View through the tool engagedwith a battery clamp.

Figure 2 is a vertical sectional View through the improved tool, showingthe same engaged with a battery clamp.

Figure 3 is a section on the line 33 of Figure 1.

Figure 4 is a perspective view of one jaw of the tool.

Figure 5 is a cross sectional View on the line 5--5 of Figure 1.

Figure 6 is a cross sectional view on the line 6-6 of Figure 1.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 represents a conventional storage batteryhaving a post 6.

Numeral 1 represents the usual battery terminal clamp which consists ofthe split annulus 8, the split end being provided with lugs 9 throughwhich the usual retaining bolt I is disposed. 35 This clamp is usuallyprovided with a socket construction II for receiving one end of thebattery cable l2.

In carrying out the present invention which is generally referred to bynumeral I 3, it can be 40 seen that the same consists of a handle l4 ofwood or some other suitable material having the elongated recess lextending inwardly therefrom from one end, at which end a pocket I6 isprovided for the purpose of permitting spreading 45 of the jaw plates I'!l8 therein. The upper ends of these jaws are provided with reducedextensions l9 having openings 20 therein through which the connectingrivet 2| is disposed and through which the pin 22 is disposed, the pindisposed entirely through the handle and headed at each end thereof. Thelower ends of the plates l1--l8 are beveled at their outer sides as at23 so that when the jaw plates l1-l8 are brought together a sharp edgeis provided which will facilitate the insertion of the lower portion ofthe tool between the lugs 99 of the battery clamp. 5 The lower beveledportions of these jaw plates Il|8 are notched out as at 24 so that thelower portion of the tool can straddle the usual clamp retaining bolt inas suggested in Figure 3.

A screw 25 having the wing construction 26 thereon preferably coveredwith insulation is threaded through the plate Hi.

In the use of the tool, the screw 25 is unscrewed outwardly so that theplates l|l8 are snugly together. The beveled lower ends of the platesll-IB which are now together can be driven downwardly so that thebifurcated lower end of the tool will straddle the bolt II].

By now driving the screw 25 inwardly so that the inner end rides againstthe plate I1, the plates or jaw plates l'|-l8 will be spread apart andconsequent action on the clamp will be that the lugs Ill-l9 will bespread apart, that is, after the nut on the bolt I 0 has been loosened,to the end that the clamp will be loosened on the battery terminal 6.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing 30 from the spiritand scope of the invention as claimed hereinafter.

Having described the invention what is claimed as new is:

A tool for use in removing a battery clamp having split ends, said toolcomprising a handle, a pair of resilient jaws of platelike form rigidlyconnected at one end to said handle, said jaws being normally closetogether at their free ends for insertion between the split ends of saidclamp and relatively separable to spread said split ends apart, saidfree ends of the jaws having straight inwardly beveled edges,respectively, to facilitate their insertion between the split ends ofsaid clamp and said free edges being bifurcated to straddle the bolt ofsaid clamp, and means operative to separate said jaw, comprising a wingbolt threaded through one jaw for manipulation against the inner side ofthe other jaw.
